Code93Symbology Class

Namespace:: ActiproSoftware.Windows.Controls.BarCode

Assembly:: ActiproSoftware.BarCode.Wpf.dll

Represents a bar code symbology implementation for Code 93.

public class Code93Symbology : LinearBarCodeSymbology

Inheritance:: object Visual UIElement FrameworkElement BarCodeSymbology LinearBarCodeSymbology object

Derived:: Code93ExtendedSymbology

Remarks

Code 93 is a linear symbology, designed in 1982 by Intermec to provide a higher density and data security enhancement to Code 39. Each Code 93 character is divided into nine modules and always has three bars and three spaces. This symbology is primarily used by the Canadian postal office.

This symbology can encode numbers, uppercase letters, and -. $/+% characters.

Each encoded value must start and stop with *, which is automatically inserted. The AreStartStopCharactersVisible property determines whether these start/stop characters are included in the DisplayValue.

This symbology implementation auto-calculates and inserts two check characters.

An extended implementation of Code 93 is available in Code93ExtendedSymbology. That implementation allows for all lower 128 ASCII characters to be encoded based on the core Code 93 concepts.
